Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Betätigung einer Parksperre eines automatisiert betätigten Getriebes eines Kraftfahrzeugs, wobei die Parksperre mittels einer Rückstellfeder in eine aktivierte Stellung bringbar ist und mittels eines Aktuators aus der aktivierten Stellung in eine deaktivierte Stellung bringbar ist, und die einen Halteaktuator mit einem Elektromagneten aufweist, der im bestromten Zustand die deaktivierte Parksperre in der deaktivierten Stellung hält.The The present invention relates to a device for actuation a parking lock of an automated transmission a motor vehicle, wherein the parking lock by means of a return spring can be brought into an activated position and by means of an actuator from the activated position in a deactivated position can be brought is, and has a holding actuator with an electromagnet, in the energized state, the deactivated parking lock in the deactivated Holding position.

Eine
Vorrichtung gemäß des Oberbegriffs ist aus der
deutschen Offenlegungsschrift
Es stellte sich die Aufgabe, eine Vorrichtung zur Betätigung einer Parksperre eines automatisiert betätigten Getriebes eines Kraftfahrzeugs zu schaffen, welche besonders einfach und kostengünstig und darüber hinaus möglichst kleinbauend und energiesparend realisierbar ist.It set itself the task of a device for actuation a parking lock of an automated transmission to create a motor vehicle, which is particularly simple and inexpensive and In addition, as small as possible and energy-saving is feasible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Aktuator die Parksperre über einen Bowdenzug betätigt, dass zwischen dem Aktuator und dem Bowdenzug der Halteaktuator angeordnet ist, der einen Elektromagneten und mindestens ein bewegliches Element aufweist und dass der bestromte Elektromagnet das bewegliche Element fixiert und dadurch eine mechanische Kopplung zwischen dem Aktuator und dem Bowdenzug herstellt.These The object is achieved according to the invention that the actuator actuates the parking lock via a Bowden cable, arranged between the actuator and the Bowden cable of the holding actuator is that of an electromagnet and at least one movable element and that the energized electromagnet, the movable element fixed and thereby a mechanical coupling between the actuator and the Bowden cable manufactures.
Die mechanische Kopplung zwischen dem Aktuator und dem Bowdenzug kann hierbei insbesondere durch ein zweites klammerartiges bewegliches oder feststehendes Element gebildet sein oder aber auch durch eine Fläche eines zur Vorrichtung gehörenden Gehäuseteils, welche(s) ein Widerlager zu dem mindestens einen beweglichen Element ausbildet. Hierbei ist es vorteilhaft, dass der Elektromagnet nur eine verhältnismäßig geringe Haltekraft aufbringen muss, welche ausreichend ist, das bewegliche Element gegen das Widerlager zu halten. Die erforderliche Haltekraft ist relativ gering, da sie senkrecht zur Betätigungsrichtung der Parksperre wirkt. Der Elektromagnet kann so relativ kleinbauend und kostengünstig ausgeführt sein. Vorteilhaft ist auch, dass der Elektromagnet mit einer vergleichsweise geringen Stromstärke betrieben werden kann.The mechanical coupling between the actuator and the Bowden cable can in this case, in particular by a second, clip-type movable or fixed element or be formed by a Surface of a housing part belonging to the device, which (s) an abutment to the at least one movable element formed. It is advantageous that the electromagnet only a relatively low holding power whichever is sufficient, the movable element must to hold against the abutment. The required holding force is relatively low, as they are perpendicular to the direction of actuation the parking brake works. The electromagnet can be so relatively small and be carried out inexpensively. Advantageous is also that the electromagnet with a comparatively small Amperage can be operated.
Darüber hinaus ist es vorteilhaft, wenn eine Feder vorgesehen ist, welche das bewegliche Element des Halteaktuators vom Widerlager wegdrückt, wenn der Elektromagnet unbestromt ist, so dass sich in diesem Fall eine definierte Stellung der Elemente relativ zueinander ergibt. Besonders vorteilhaft ist, dass hierzu eine nur geringe Federkraft benötigt wird, so dass diese Feder einen nur geringen Einfluss auf die erforderliche Stärke des Elektromagneten hat.About that In addition, it is advantageous if a spring is provided, which the movable element of the holding actuator pushes away from the abutment when the electromagnet is de-energized, so that in this case a defined position of the elements relative to each other. Especially It is advantageous that this requires only a small spring force so that this spring has only a minor effect on the required Strength of the electromagnet has.
Besonders vorteilhaft ist es, wenn die Vorrichtung einen Anschlagblock aufweist, dessen Form an die äußere Form der gegeneinander beweglichen Elemente angepasst ist und zwar dergestalt, dass der Anschlagblock das bewegliche Element aus der geöffneten Stellung wieder schließt, wenn der Halteaktuator gegen den Anschlagblock bewegt wird. Hierdurch wird erreicht, dass die Magnetkraft des Elektromagneten nicht dafür ausgelegt zu sein braucht, das bewegliche Element mit dem Widerlager zusammenzuführen, sondern lediglich dazu, diese nach dem Zusammenfügen zusammenzuhalten. Da die Haltekraft um ein Vielfaches geringer als die über einen Abstand wirkende Anzugskraft, führt dies ebenfalls zu einer erheblichen Einsparung bei der Dimensionierung des Elektromagneten.Especially it is advantageous if the device has a stop block, its shape to the outer shape of each other is adapted to movable elements in such a way that the Stop block the movable element from the open Closing position again when the holding actuator counteracts the stop block is moved. This ensures that the Magnetic force of the electromagnet not designed to needs to be to merge the movable element with the abutment but only to hold them together after assembly. There the holding force many times lower than the over a distance-acting tightening force, this also leads to a considerable saving in the dimensioning of the electromagnet.
